Error Handling Strategy Demo

This project includes an end-to-end example implementing the articles:

• Single error model DomainError
• Central handleError processor
• Five boundaries: server, network, interaction, rendering, browser

Key files:

• Core: src/error/*
• Server Actions: src/app/actions/auth.ts
• API Routes: src/app/api/users/*
• Client Boundaries: src/components/BrowserBoundary.tsx, src/components/ErrorBoundary.tsx

Demo pages:

• /sign-in – Interaction boundary with safeServerAction
• /users – Server component fetching with error.tsx route boundary
• /users/[userId] – Client fetch via networkBoundary + render boundary

Setup:

1. Install deps: pnpm install (or npm i)
2. Start dev: pnpm dev
3. (Optional) set NEXT_PUBLIC_BASE_URL=http://localhost:3000 for server component fetch base
